Does this use too much electricity? If i turned the bass off and play on low volume will i save electricity?

Depends what you class as 'too much'. Electricity consumption in the UK is measured in 'units' these are kilo-Watts per hour (1kWh=1 unit). You can check your electricity bill for how much a unit costs; it's probably around 14p. These speakers are rated for 500W of output, and whilst this is theoretically a continuous rating, it's more accurate with consumer speakers as a 'peak' rating. So essentially, a full-spectrum noise (like an explosion) playing at full volume (BEFORE distortion occurs) will use 500w, or 0.5kWh if that noise was continual for an hour. A quieter noise will use less, though there is a law of depreciating returns in effect here (so a noise that you perceive as half as loud will use more than half as much electricity). So in essence, the most these speakers can cost to run is 7p per hour.I have the predecessor to these set up and monitored for consumption (consumption won't really have changed much as speakers don't get more efficient; there are laws of physics at work). I don't ever really turn the volume above 20% or else my housemates/neighbours will complain. It is good to have this headroom though as the fidelity (read: sound quality) of what you're listening to will be much higher in the lower volume range. They use around 2p-3p per hour at this point depending on what I'm listening to.

Why the price is changing so fast? Yesterday i decided to buy this but today i see the price jumped from 149 to 207 !

It depends on which direction the wind is blowing

To use this with my TV would I have to buy a separate AV receiver?

No, you can connect the Z-906 via optical/Digital cable. Z-906 has a seperate amp built into the subwoofer. I connect the Z-906 to my playstation and T.V via optical, it works perfect. Hope this helps.

I own this speaker system, it is incredible. I am just wondering what are the wires that connect from each speaker to the subwoofer called?

The subwoofer has the amplifier built in the box and I believe they just use standard speaker leads just audio lead thats all I know, I will let you know one thing be warned the wires that come with the unit are very short for the rear speakers. hope this helps.
